My Goldschmidt

Role functions

Committees

Shuhei Ono is Associate Professor in Low Temperature Geochemistry at the Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology. His research group develops and applies novel isotope proxies to trace evolution and interaction between microbe and geochemistry. Recent research topics include application of tunable laser spectroscopy for precise measurements of clumped methane isotopologue and its application to define diverse origin of methane in the environment. He is a co-chair for Boston Goldschmidt 2018

Roberta Rudnick is a professor in the Department of Earth Sciences at the University of California, Santa Barbara. Her research focuses on the origin and evolution of the continents, particularly the lower continental crust and the underlying mantle lithosphere. Emphasis is placed on integration of data from a wide diversity of sources, including petrography, petrology, major and trace element geochemistry, stable and radiogenic isotope geochemistry, and geophysics in order to determine the bulk composition of the crust, the processes that have influenced its composition through time, and why the Earth has continents. She is a Geochemistry Fellow and a Fellow of the American Geophysical Union.

Ann Pearson is the Murray and Martha Ross Professor of Environmental Sciences at Harvard University. Her research focuses on applications of analytical chemistry and isotope geochemistry to Earth and environmental processes. Through studying the chemistry of natural organic molecules, her work yields insight about conditions on Earth today, in the past, and about potential human impacts on our future. Recent projects have focused on understanding pathways of lipid biosynthesis relevant to the global carbon and nitrogen cycles and paleoclimate, and on new technologies for biomolecular stable isotope analysis. Pearson received a Fellowship for Science and Engineering from the David and Lucille Packard Foundation in 2004, a Radcliffe Institute Fellowship in 2009, and was named a Marine Microbiology Initiative Investigator of the Gordon and Betty Moore Foundation in 2012.

I graduated magna cum laude in 1998 with a B.Sc. in marine science and chemistry from the University of Miami in Coral Gables, FL. After a one-year stint working at the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory, I began graduate school in the Department of Geosciences at Princeton University. Graduating with a Ph.D. in 2004, I subsequently became a postdoctoral researcher at the University of Washington with a fellowship from the Joint Institute for Study of the Atmosphere and Ocean (JISAO). I joined the faculty at Brown in 2008, and continue to pursue my varied research interests in the global N cycle, the biogeochemical record in ice cores and global connections between atmospheric chemistry and climate. My interest in reactive nitrogen (e.g., NOx) extends from its connection to air quality through its impact on ozone and hydroxyl concentrations to the biogeochemical cycling of nitrogen in the earth system via formation of nitric acid (or nitrate), a major component of acid rain and a source of biologically available nitrogen.

Ethan Baxter is an isotope geochemist & geochronologist interested in the rates and timescales of petrologic and tectonic processes occurring within and between the Earth’s crust, mantle, and surface. He received his B.S. in Geology and Geophysics from Yale University in 1995 and his Ph.D. in Geology from the University of California, Berkeley in 2000. After a two year post-doctoral fellowship at the California Institute of Technology (Caltech), he was a member of the Dept. of Earth Sciences at Boston University from 2002-2015. He joined the faculty at Boston College in July 2015 and is now professor and chair of the Dept. of Earth & Environmental Sciences. At Boston College, he directs the new BC TIMS Facility. In 2007, he was awarded the Clarke Medal by the Geochemical Society for an "outstanding contribution to geochemistry or cosmochemistry by an early career scientist". In 2011, he was named a Mineralogical Society of America Distinguished Lecturer.
